SHANK AND HEEL BURNISHING MACHINE.

SPECIFICATION forming part of Letters Patent No. 369,679, dated Sept-ember 13, 1887,

Application filed November 11, 1886. Serial No. 218,658. (No model.)

To all 1071,0112. it may concern:

Be it known that 1, ROBERT ASHE, of Somerville, in the county of MiddleseX and State of Massachusetts, have invented certain new and useful improvements in Shank and Heel Burnish'ing Machines, of which the following, taken in connection with the accompanying drawings, is a specification.

My invention relates to that class of burnishing-machines employed to burnish the soles of boots and shoes, especially the shanks thereof, my invention being also applicable for burnishing top lifts of heels.

The main object of my invention is theproduction of a burnishing-machine wherein the motion of the. burnishing-tool may be changed at the will of the operator from an elliptical to a substantially right line movement, or Vice versa, and in my invention as herein embodied I have provided means whereby this change of movement may be produced while the machine is in operation.

Figure 1 is a side elevation of a sufficient portion of a heel-burnishing machine embodying myinvention to enable it to be understood. Fig.2 is a left-hand elevation of Fig. 1. Fig. 3 is a sectional detail of the connecting-bar (to be described) and its method of attachment and the shaft for moving it. Fig. 4 is a detail showing the front end of the main shaft, the

block fitted therein, and the stud-screw carried by it. Fig. 5 is avertical section of Fig. 2, in the line 00 00. Fig. 6 is an enlarged sectional detail of one part of the lever carrying the burnishing-tool. Fig. 7 isasection of Fig. 6 in the line 00", and Fig. 8 is a sectional detail (to be referred to) taken through the connecting bar and rod.

In the accompanyinying drawings, A A A, Figs. 1 and 5, is the frame of the head of my machine, it having boxes m w, in which is mounted the driving-shaft B, provided with the handwheel and pulleyO. The front end of the shaft 13 has fastened to it a collar, B, provided with a T-shaped groove, in which is fitted a block, B", which block is held in its place by aset-screw, 13 Fig. 3. A stud-screw, B", inserted in the block B, receives upon it the connecting-bar D, Figs. 1, 3, and 5. The connecting-bar D is bored longitudinally to receive a rod, D, this rod being retained in 'workmans foot.

place by a collar near its lower end and by a washer and pin, D at its upper end, as shown in Fig. 5. The connecting-bar D is also provided with a T-shaped groove, (see Fig. 8,) extending nearly the length of the rod D, in which groove is fitted a block, D journaled on the stud D, fastened to a slide-bar, E, the said stud being held in place by a nut, D Figs. 1, 5, and 8.

The slide-bar E is fitted to run easily in suitable guides in the bracket E, and is held in its place by the caps 0, Figs. 1, 2, and 5; or it may be fitted in a dovetail groove, in which case no caps, 6, would be required.

The slide-bar E has a pin, E, which strikes against the bracket E and limits the upward movement-of the slide-bar, the bar being normally retained in its elevated position by a spring, e,Fig.2. The bracket E,having a stud, E, is adjustably held to the frame-work.

E, Fig. 1, is a lever pivoted at Ff, one end of which is connected by means of the rod E* to a lever or treadle attached to the 'floor, which lever or treadle is operated by the The slide-bar E has attached to it a small bracket provided with. a pin, E,

having a roll, E which is just under the front end of the lever H Figs. 1 and 5, is a lever which is journaled between the lugs or jaws H", Fig. 2, on the pin H. .The seat of the lugs or jaws H is a collar, 0, which rests on a base or suitable support in the frame A, Figs. 1 and 5. Projecting downward from O is a pin, H on which is a collar, H. This collar is held in its place by the screw H WVhat I will call the back end of thelever H has fitted in it a pin, H, Figs. 1 and 5. The ends of the rods H and D form a joint at H. Now, if the shaft B be revolved it will transmit motion through the crank-pin B to the connecting-bar D, and through bar D and its rod D to the rod H and lover H. also clear that as the upper end of the bar D is carried around by the crank-pin 13* the block D serves as a fulcrum on which it will swing, thereby causing the burnisher H" to move in an elliptical path.

Fig. 6 is asection (full size) of the front end of the lever H and Fig. 7 a cross-section of the same.

It is- In Fig. 6 H is a sleeve or bushing fitted to a hole in the lever. Near the back end of this sleeve there is a slot, H through which passes the pin H. This pin also passes through the lever, in which it is firmly held. (See Fig. 7.) Behind the sleeve H is a spring, H It will be seen that the spring keeps the sleeve H pressed forward, so that the back end of the slot is against the pin H, and also that the said pin prevents the sleeve turningin its place. H is a pin driven into the sleeve H, but not projecting beyond its surface.

H is a burnisher, from which extends a stem, E. This stem or shank is slotted in the end and made to fit the sleeve H". The slotted end of the shank or stem of the burnisher allows it to pass by the pin H and prevent the burnisher turning in its place.

H is a spring, one end of which is bent so as to allowits dropping into the notch H". It is fastened on the lever H by the screw H. The shank or stem of the burnisher has a depression upon it at the notch H", the bottom of said depression being parallel with the axis of the stem for a short distance, when it gradually rises to' the surface, forming an inclined plane, on which the spring H acts to retain the burnisher in its holder. The flat part oi the depression on the stem of the burnisher permits of the burnisher being advanced against the spring H thereby giving the burnisher in its holder that elasticity which in practice is found to be desirable. The end of the burnisher-stem is beveled, so that it will easily slide under the end of the spring H when being inserted in its place.

In operation the workman holds the-boot or shoe to be burnished in his hands and-moves the shank part of the sole or the top lift of the heel (as the case may be) against the burnisher. I

When bur-nishing shanks,it is desirable to follow the line across the sole at the ball of the shoe with great accuracy. It is also desirable to get close in the corner formed by thejunction of the sole and the breast of the heel, and at the same'time avoid the rapping of the burnisher against the heel-breast. These re sults are accomplished in my machine by the operator pressing his foot upon the treadle or lever on the floor that is connected by the rod E to the lever E thereby pressing the back end of lever E upward. The other end of said lever being forced down carries with it the slide-bar E, nut D stud D", and'block D It is evident that as the block D is moved downward toward the lower end of the connecting-bar D the horizontal movement ofthe lower end of said bar and of the parts operated by it will be decreased until the burnisher will onlyhave movement in a rightline, and, as herein shown, in a vertical plane, such movement enabling the operator to easily follow a line across the sole with great exactness. Upon the workman releasing the foot treadle or lever on the floor the spring before referred to draws the slide-bar E up .to its normal posi tion. Vitlaa burnishing-tool of suitable form the edges of heels can also be burnished on my machine.

Having now described my invention, what v I claim,and desire to secure by Letters Patent,

1. In a burnishing-machine, the burnishingtool, the pivoted lever to carry it,and the link jointed to the said lever, combined with means, substantially as described,whereby the movement of the said tool may be changed froman elliptical to a substantially right-line movement, or vice versa, at the will of the operator, for the purposes set forth.

2. In a burnishing-maehine, the connecting-bar D, provided With a pivotal rod, D, and a groove adapted to receive a journaled block, D as herein set forth and described.

3. In combination with the connecting-bar D and its pivotal rod D. the rod H, lever H toggle-pieces H and H arranged and operating as herein set forth and described.

4. In combination with the connecting-bar D and pivotal block D the sliding bar E, as herein described, and for the purpose set forth.

5. In a burnishing-tool holder, in combination with the spring H .spring H pin H, and pin H, the sleeve H", adapted to receive and hold aburnisher, said burnisher bering capable of movement against the spring H and under spring H at the same time, as herein described and set forth.
